A new rumor surfaced on the product that will sit inbetween the GeForce GTX 1080 and Titan X (Pascal), the 1080 Ti surfaces again. Word right now is that the card will be released in the CES timeframe (1st week of January 2017).
The rumor originates from zol.com.cn who also claims a 1503 GPU frequency with a 1623 Boost freuqency. But they might have well taken the specs from charts like ours (we can calculate stff like TMUs/ memory bandwidth and GFLOPs based on specs)
The product has 52 shader clusters (SM) totalling towards 3328 shader processors and DDR5 memory. The GeForce GTX 1080 Ti will be using the GP102 silicon, similar as used for Pascal TitanX, however it has 4 out of 30 shader processor clusters disabled, so that is 3,328 shader processors. If you do the math then your TMU count would get to 208 with a ROP count of 96. According to the screenshot the GPU itself will be clocked at 1503 MHz and 1623 MHz on the GPU Boost. Two things really jump out here, the memory remains GDDR5 not GDDR5X as Pascal Titan X is using and then the shader count has been decreased towards 3328 shader cores, which is still 768 more compared to the GeForce GTX 1080.
The numbers add up tyowards a 10.8 GFLOP/s single precision performing product. Charted up it looks like this:

GDDR5 memory would bring in 384GB/s of memory bandwidth, which would be the deal-breaker over a Titan X with its 480GB/s of bandwidth. It is still more then the 1080 though. The card will get a 250 Watt TDP. Pricing wise we know nothing of course, but the 1080 is at 699 USD, the Titan X at 1200 USD .. so somewhere in the middle ?
We are not sure why the product qould launch at CES though, if DDR5 is used, productions should not be an issue and the Christmas season would make way more sense.
